I have a 2011 A/C Revolution whose house batteries are not being charged by the engine alternator. I have 14.4 volts at the charging relay from the engine (when running) and I have 12.6 volts on the other side of the relay from the house batteries.
Is this an automatic charge when engine is running?
Do I have to activate a switch to get the relay to engage?
I have a yellow secondary wire on one side of the relay and a white/black secondary wire on the other side. The yellow wire is not energized when engine is running and I can't get to the black & white wire to see if I have power to the relay.
Does anyone know which is ground and which is hot and what activates the hot side of the relay?
